Description

  The present invention relates to a water storage device that can store a certain amount of tap water that is always kept fresh.

  Water is indispensable for living, but if a major disaster occurs, the supply from the water pipe may stop. For this reason, it is necessary to ensure the emergency water for drinks as a self-defense means at the time of a disaster. Therefore, a technique for storing a certain amount of tap water has been proposed so far (Patent Document 1).

  According to this invention, water flows sequentially by the use of tap water, and water is always secured in the water storage flow path constituted by these tubular members without dead water. In an emergency, the air valve is opened by opening the lower water supply curan, so that water flows down from the vicinity of the bottom of each tubular member, and all the water stored in these tubular members can be used. (See summary, solution).

  In the above invention, when the water in the water storage channel is desired, it is assumed that almost all the water in the tubular member can be discharged by simply opening the water supply currant (see paragraph [0032]).

  However, in an emergency when the supply of tap water from the water main is interrupted, if the water in the tubular member is discharged just by opening the currant, it is indistinguishable from the normal time when the tap water is supplied. There is a risk of consuming it without knowing that it should be used.
